Title: Design of Concrete Structures for Thermal Effects
Author(s): J. Pajuhesh
Publication: Journal Proceedings
Appears on pages(s): 74-77
Keywords: cracking (fracturing); expansion; loads (forces); moments; reinforced
concrete; relaxation (mechanics); stress-strain relationships; structural
design; thermal properties; thermal stresses.
Abstract:Investigation of the thermal relaxation problem is extended beyond an earlier paper by developing an interaction diagram type of solu tion for design of reinforced concrete sections subject to relaxing-type loading (such as effects of thermal force and moment) in addition to sustained-type loading (such as vertical loads). The formulation is presented for a parabolic stress-strain relation for concrete and a given set of design criteria. The formulation of the solution is generalized to make the interaction diagram approach more readily available, and samples of specific diagrams are shown. Finally, a comparative study is made for a numerical example to indicate the importance of considering thermal effects.
